Release notes#

FMIR package binary / package MIR target docs and final target descriptions. This release builds the complete FMIR (Faber MIR) packaging pipeline across three image formats — text, binary, and self-contained executable — and closes the scena package target. On the planning side, the tensor systems campaign timeline and shaped-value definition land alongside a clean-break retirement of several obsolete source surfaces.

Scale#

Major tracks#

FMIR package binary pipeline#

The MIR package binary campaign is established, executed, and documented across three image formats:

• FMIR text image floor: add the base text-format image target, including lexer tokens (fmir_text, fmir_bin), MIR ABI extensions, and semantic type wiring (bd1d4baa6).
• Text image hardening: robust loading with deserialization error handling and round-trip validation (1fc6b1268).
• Type metadata serialization: Radix serializes full type metadata into the FMIR text format, covering precision, numeric width, and type index data (751d49f14).
• CLI argument binding: runtime CLI arguments are bound to FMIR text image parameters through the runner's invocation path (ebc2d715c).
• Normalized package runner: the FMIR stepper loader boundary is refactored into a consistent runner abstraction shared across formats (6f3770e70).
• FMIR binary image target: add a compact binary image format with its own target and package surface (537162870).
• FMIR executable bundle target: produce a self-contained native executable that bundles the MIR image with a stepper harness (4709762dc).
• Executable runner embedding: the bundled executable runner is wired end-to-end through the radix codegen pipeline, package build commands, and integration tests (9bcb6c89a).
• Polish and final descriptions: preserve raw FMIR source paths, align fmir-exe target naming, and describe final package targets in README and help docs (b2ab1d213, 3b46a8c56, 6ec050ebd).

Campaign docs manage the lifecycle: open, close, reopen for the expanded FMIR scope, record the native packaging decision, and lower each stage (487142805, c22a621a1, 769b7fa64, c506e91f1, 6962cd7d5, 6075741eb, 49ec77d11).

Scena package target#

• Target commands wired: scena package target commands are integrated into the faber-cli CLI, radix codegen coverage, driver, and semantic passes (1f04710c2).
• Target capability advertised: the scena target is listed in the capability matrix, help docs, and radix targets output (9c9a40521).
• Runtime requirements declared: scena artifacts declare host runtime requirements via a manifest (e7bb55770).
• CLI exit gap burned down: scena CLI exit behavior is hardened with expected-failure tests and gap analysis (4cf67de54).
• Artifact harness floor: test harness coverage for scena exemplars and coreutils artifact validation (f65fa1d18).
• Closeout: final packaging, delivery doc, and v0.39.0 release note update (7e12b5d74).

Tensor systems campaign (planning)#

• Tensor systems timeline: full campaign timeline with seven goal documents: tensor semantics contract, storage locus, layout views, failable runtime, packed numeric blocks, MIR tensor operation parity (289d8db3e).
• Semantics refined: narrow the tensor semantics contract, clarify neighbor types, and mark the tensor lane as MIR-first (7cb2ef013, 97db4d7bb, f82bc889f).
• Shaped values defined: MIR-first shaped value family documented with scalar elements, storage locus descriptor facts and first-slice conventions (7c6cacd45, ecbcb6f92, 51f638846, 79339bbc1, 68f9159df).
• Campaign structure: campaign made implementation-shaped with extended end-to-end roadmap, locked MIR stepper target, locked model fixture, and tensor sectio view-producing semantics (b084394bb, 5b58312d9, 7e2f581a3, 733e5ebb3, 2da5f2503).

Retired surfaces clean break#

• Clean-break goal: retire externa, subsidia, and HAL as source surfaces; retain @ verte as a time-boxed exception until the unified package manifest resolves codegen template placement (237c9f7f1, 025110475).
• Externa and subsidia removed: all externa/subsidia source fixtures, codegen paths, parser/syntax promotion, annotation lowering, and exempla fixtures are deleted. Target policy simplified (255976d07).
• HAL surface references purged: runtime HAL fixture files, library import paths, and documentation references to the retired HAL surface are removed (17168bb92).
• Stale wording removed from EBNF, README, and target capability matrix (6d829af3d).
• Verte alias residue and Zig target mentions cleaned up (8722442f6, 62b11b670).
• Legacy error fixtures replaced with fac cape equivalents (e626ac9b7).

Other changes#

• External library home: factory goal and implementation for resolving libraries from an external home directory; replaces the 2800+ line norma stdlib directory with a slim external lookup path (9a7b22258, d214d84d8). Clippy lint satisfied (067bca00e).
• Unified package manifest: planning doc for a single canonical manifest format replacing the split faber.toml / cargo.toml world; Phase 3 text-scan claim corrected (fbdb1f412, 664bfa288).
• Norma retirement CI: test adjustments to keep fast CI green while the norma stdlib directory trees are removed (fa58e2013).
• Worktree home standardized: worktree convention doc and audit script aligned (2526c75a5).
• Stale external declaration comments removed from syntax modules (682562cb5).
• Modulus namespace wording retired across stdlib docs and scripts (5d1c56851).
